Figure$1$ of $1$

An inclined surface extends upward and leftward so that the surface lies along the hypotenuse of a right triangle with its horizontal leg of $4$ units, a vertical leg of $3$ units, and a hypotenuse of $5$ units. A straight horizontal beam is rocker supported on the inclined surface with its left end $\text{'}$A$\text{'}$ and pin supported on a horizontal surface with its right end B$.$ A distributed load acts vertically downward on the beam. The load first increases linearly from $0$ at point $\text{'}$A$\text{'}$ to w at the midpoint of the beam $3$ meters away from the ends. Then it decreases linearly back to $0$ at point B$.$ The x y plane is shown. The x axis is directed to the right, and the y axis is directed upward.
